A federal appeals court has ruled against pilots from the old America West airlines in their dispute with their union at US Airways.

The two airlines combined in 2005, but their pilots are still fighting over seniority rights. Six pilots from the old America West sued their union, saying it planned to ignore an arbitrator's decision that it believed had favored the America West pilots. Last year a judge agreed with the America West pilots and ordered the union to follow the arbitrator's decision.

Friday's decision from a three-judge panel of the 9th U.S. Circuit Court of Appeals says it's too soon to say that the union has harmed the America West pilots because a new contract would have to be ratified first.
